Customers are impressed with the air quality improvement and quiet operation of this 22" air purifier tower. Many appreciate its ease of use and odor removal capabilities, along with the added benefit of a UV light. However, some customers express concern regarding the filter replacement cost and its coverage area. While some experienced allergy relief, others found it didn't completely eliminate their allergy symptoms.

    Love my germguardian. I use it at night for some nice white noise. It’s a little loud, so those who want a quiet product should go with something else.
